    Abstract: An electrically-actuated variable camshaft timing (VCT) assembly includes a gearbox assembly including an input; an electric motor having a rotor, a stator, and a motor shaft that is coupled with the input of the gearbox assembly, wherein the motor shaft includes etchings, on an outer surface of the motor shaft, that releasably couple the motor shaft to the rotor at a center aperture of the rotor when an amount of torque exerted on the motor shaft via the gearbox assembly is less than or equal to a predetermined torque value, and the etchings are further configured to decouple the motor shaft from the rotor when the amount of torque exerted on the motor shaft is greater than the predetermined torque value.
